摘要
随着切眼断面尺寸的越来越大,常规的巷道支护技术已经满足不了煤矿需求了,采用锚杆支护技术是一个不错的选择。通过对锚杆支护技术的理论及参数设计进行研究,将锚杆支护技术应用到汾矿集团某煤矿中进行分析,结果显示锚杆支护效果非常好,这也说明了在大跨度切眼巷道中选择锚杆支护技术是可行的。
As the cut section size is more and more big, the regular of roadway supporting technology already cannot satisfy the requirement of coal mine, the bolt support technology is a good choice. Through theory and parameter design of bolt support technology, bolt support technology applied to Fen mining group in a certain coal mine were analyzed, and the results show that the bolt support effect is very good, this also shows in large-span selection during roadway bolt support technology is feasible.
